Alastair is a member of the Electrochemical Science and Engineering group, which spans several schools across Imperial College London. Alastair’s existing work is focussed around the thermal management and thermal effects of lithium-ion cells. Alastair led the work introducing the Cell Cooling Coefficient as a universal metric to quantify the thermal performance of a battery. He is now building upon this research to develop capability for cell design optimisation using the Cell Cooling Coefficient.

Background: Alastair completed a PhD in Mechanical Engineering at the University of Bristol in 2016, specialising in multiphase fluid flow with an emphasis on transient heat transfer. Prior to joining Imperial College London in 2018, Alastair worked for SUEZ Advanced Solutions UK, designing equipment closely linked to his PhD topic, and as a Research Associate at Queen Mary University of London, modelling convection cooling capabilities of low powered air-moving devices.
